Delayed Mode TSG data of the SURVOSTRAL project

Written by Elodie Kestenare in May 2010 (last updated: July 2020)

  • Project: SURVOSTRAL international program
  • Description: In-situ sea surface temperature and salinity from the TSG installed on the Astrolabe vessel (IPEV)
  • Period: 1993-2020
  • Area: Southern Ocean between Hobart (Tasmania) and Dumont d'Urville -the French Antarctic base-
  • Source: LEGOS, France
  • contact: Rosemary Morrow or Elodie Kestenare at LEGOS


The delayed mode datasets are available for two different periods: 1993-2002 and 2002-2017


I. Delayed-mode data, 2002-2017
The data are freely downloadable here (see README.txt file for details)
Netcdf files are at the GOSUD format

II. Delayed-mode data, 1993-2002
The data are freely downloadable here


III. Other products

Data are also available on request.
